我正在制作一个自定义主题，并编辑了评论。php，但我无法将这些评论保存为对另一条评论的回复。我已经成功地将注释父id显示为源代码中的隐藏值，但它没有相应地将其保存在数据库中（相反，它总是将注释父id保存为0）。此外，由于某种原因，也没有保存评论者IP地址（comment\\u author\\u IP显示为“：：1”）。以下是我目前掌握的代码：

    <?php
    if ( post_password_required() )
        return;
?>

    <div id="comments" class="comments-area">

    <?php // You can start editing here -- including this comment!

    $fields = array(
    \'author\'               => \'<p class="comment-form-author"><label for="author">\' . __( \'Name\', \'domainreference\' ) . \'</label> \' . ( $req ? \'<span class="required">*</span>\' : \'\' ) . \'<input id="author" name="author" type="text" value="\' . esc_attr( $commenter[\'comment_author\'] ) . \'" size="30"\' . $aria_req . \' /></p>\',
